f.lux issue with screensaver on macOS

Hello, I’m using screensavers to boost my creative thinking and get a quick break. Flux, however, also seems to be taking a break: Each time I exit the screensaver (e.g. by hitting a key) at night, Flux is turned off. Only after a second or so does it dim the screen colours again. This ”flash of daylight” is hurting my eyes. Anything you can do to make Flux run all the time, even with Mac OS screensavers?
